The following result was previously stated and proved in [1]}
for the genealogies of Cannings' models.
Here we emphasize that the same statement, and in fact the same proofs, remain
valid (verbatim) in the context of the more general
discrete-time coalescent processes defined as in (REF ). In
particular they remain valid for (non-Canings') populations with asymmetric offspring distributions. Here we thus
only enunciate the result, and refer the reader to [1]} for its proof.
